Isolate an input or the program in a separate window (WebRTC)

Isolation URL allow you to open a specific input in another tab or device. 

With the isolation URL you can do :

- ISO Recording of a remote capture input locally
- ISO recording of a remote capture input in LiveU Studio (in another control room)
- Display a remote guest on a TV / screen in Studio mode in front of the artist / Host

Please note that this URL is only available in the testing or publishing phase.

This is not a link intended for the audience. In order not to overload the server, the link cannot be opened more than 3 times simultaneously.

To find the Isolation URL of an input:

  • Open the control panel of the wished input (A).
  • Copy the provided isolation URL (B).
